WARNING
xThis Instruction Sheet only provides descriptions for electrical specifications, general specifications,
installation & wiring, troubleshooting and peripherals. Other detail infromation about programming and
commands is compatible with ELC-PC/PA/PH series; please see ELC Application Manual. For more
information about the optional peripherals , please see individual product manual.
xThis is an OPEN TYPE Controller. The ELC should be kept in an enclosure away from airborne dust, humidity,
electric shock risk and vibration. Also, it is equipped with protective methods such as some special tools or
keys to open the enclosure, so as to avoid the hazard to users and the damage to the ELC.
xNever connect theAC main circuit power supply to any of the input/output terminals, as it will damage the
ELC. Check all the wiring prior to power up. To avoid any electromagnetic noise, make sure the ELC is
properly grounded . Do NOT touch terminals when power on.
xBattery replacement: use UL component type: TDRTL-2150/S lithium battery. Refer to following table for
battery life. (NOTE: RTC should be reset after changing battery).

5 INSTALLATION & WIRING
5.1 Installation of the DIN rail
The ELC can be secured to a cabinet by using the DIN rail that is 35mm high with a depth of 7.5mm. When
mounting the ELC on the DIN rail, be sure to use the end bracket to stop any side-to-side motion of the ELC, thus
to reduce the chance of the wires being pulled loose.At the bottom of the ELC is a small retaining clip.
To remove it, pull down the retaining clip and gently pull the ELC
away from the DIN rail. As shown on the right:
When installing the ELC, make sure that it is installed in an
enclosure with sufficient space (as shown on the right) to its
surroundings so as to allow heat dissipation.

5.2 Wiring
22-16AWG
<1.5mm
1. Please use 22-16AWG (1.5mm) wiring (either single or multiple core) for
I/O wiring terminals. The specification for the terminals is as shown on the
left. ELC terminal screws should be tightened to 1.95 kg-cm (1.7 lb-in). Use
Copper Conductor Only, 60/75 °C.
2. I/O signal wires or power supply should not run through the same
multi-wire cable or conduit.
5.3 Power Input Wiring
1. When DC voltage is supplied to the ELC, make sure the power is at terminals 24VDC and 0V (power range is
20.4VDC~28.8VDC). When voltage is lower than 20.4VDC, ELC will stop operating, all outputs will turn OFF
and the ERROR LED will flash continuously.
2. If the power-cut time is less than 10ms, the ELC still operates unaffectedly. If the power-cut time is too long or
the power voltage drops, the ELC will stop operating and all the outputs will be Off.

1. ELC-PC series have two output modules, relay and transistor. See
“Function Specifications” for their specifications.
2. Please watch out the connection of common terminals whilewire the
outputs. For example, when wiring ELC-PC12NNDR/T,output
terminal Y0 uses one common terminal C0, Y1 uses C1, and Y2~Y3
share C2, as shown below:

*1: For switching direct current on inductive loads, a reverse-current protection diode should be installed in parallel
with the load. The relay contact life decreases significantly if this is not done.
The reverse-current protection diode needs to satisfy the following specifications.
- The diode is rated for maximum reverse voltage of 5~10 times the load voltage.
- The forward current is more that the load current
*2: For switchingAC on inductive loads, a surge absorber (0.1uF + “100ohm to 120ohm”) should be installed in
parallel with the load. The relay contat life decreases significantly if this is not done.
*3: Ensure all loads are applied to the same side of each ELC output, see above figure. Loads which should
NEVER simultaneously operate(e.g. direction control of a motor), because of a critical safety situation, should not
rely on the ELC’s sequencing alone. Mechanical interlocks MUST be fitted to all critical safety circuits.

transistor output, a reverse-current protection diode can be installed in parallel with the load if necessary.
The reverse-current protection diode needs to satisfy the following specifications.

- The diode is rated for maximum reverse voltage of 5 to 10 times the load voltage.
- The forward current is more than the load current.
6 TRIAL RUN
ƁPower Indication
The “POWER” LED at the front of the ELC will be lit (in green) if the power is on.
ŶLow Battery Voltage Indication
There is also a “BAT.LOW” LED at the front of the ELC. When the LED is on, it indicates that the battery voltage is
insufficient. Please change the battery (within 3 minutes) as soon as possible; otherwise the user programs and the
data in latched area may be lost.
ŶPreparation
1. Prior to applying power, please verify that the power lines and the input/output wiring are correct. And
be advised not to supplyAC110V or AC220V into the I/O terminals, or it might short-circuit the wiring
and would cause direct damage to the ELC.
2. After using the peripheral devices to write the program into the ELC and that the ERROR LED of the
ELC is not on, it means that the program in use is legitimate, and it is now waiting for the user to give
the RUN command.
3. Use ELC-HHP to execute the forced On/Off test of the output contact.
ŶOperation & Test
If the “ERROR” LED of the ELC is not blinking, use RUN/STOP switch or the peripheral devices (ELC-HHP or
ELCSoft) to give the RUN command, and the RUN indicator will then be on. If the “RUN” LED is not on, it indicates
that there is no program inside the ELC.
ELC-HHP could be utilized to monitor the settings and the registered values of the timer (T), the counter (C) and the
data register (D) during operation, and moreover, to force the output contacts to conduct the On/Off action. If the
ERROR LED is on (but not blinking), it means that the setting of the user’s program has exceeded the preset
overtime limit. At this time, please turn RUN/STOP switch to STOP and get program time-out address from special
register D1008. (it is recommended to improve by WDT command)
ŶELC Input/Output Reaction Time
The total reaction time from the input signal to the output operation is calculated as follows:
Reaction Time = input delay time + program scan time + output delay time
Input delay time Factory setting is 10ms. Please refer to special registers D1020~1021.
Program scan time Please refer to the usage of special register D1010.
Output delay time Relay module: 10ms. Transistor module: 20~30us.
ŶBasic Commands andApplication Commands of the ELC:
1. The basic commands and the application commands of the ELC of this series are totally applicable to the
ELC. Refer to the ELC Technique Application Manual for relevant basic commands and application
commands.
2. The ELC-HHP handheld programming panel and the ELCSoft (Windows version) editing program of the
ladder diagram are both good for use with the ELC. Also, the ELC could connect with the
ELC-PC12NNDR/T,ELC-PC12NNAR through specific transmission wire to execute the program
transmission, the ELC control and the program monitoring.
7 TROUBLESHOOTING
Judge the errors by the indicators on the front panel. When errors occurred on ELC, please check:
Ɓ“POWER” LED
There is a “POWER” LED at the front of the ELC. When the ELC is powered On, the green LED light will be on.
ƁELC “RUN” LED
Identify the status of the ELC. When the ELC is in operation, this light will be on, and users could thus use
ELC-HHP or the editing program of the ladder diagram to give commands to make the ELC “RUN” or “STOP”.
Ɓ“ERROR” LED
If incorrect programs are input to the ELC, the indicator will blink. Please check D1004(Error code) and
D1137(Error step number).
When the ERROR LED is on (not blinking), it indicates that the execution time of the program loop has
exceeded the time-out setting (set by D1000). Please turn the ELC RUN/STOP switch to STOP, and find out the
address of the time-out program by special data register D1008. ”WDT”. After completing modifying program,
user only need to reload program and this LED will be off at this moment. Once the LED still lights, please turn
off the power and check if there is interference or any conductive material in ELC.
Ɓ“BAT.LOW” LED
When the battery voltage is low, the “BAT.LOW” LED will be on, please change the battery within 3 minutes to
retain the ELC’s internal user programs and data).
Ɓ“Input/Output” LED
The On/Off signals of the input point could be displayed through the “Input” LED. “Output” LED indicates if the
output signals are On or Off.
